blew another (%(*## dimmer switch.... anybody know the anatomy of these??

well now that i have four bad dimmer switches, i was thinkin of takin a chance an fixin them.... there looks like just a resistor that keeps blowing on them. Anybody know how to take em apart??? im thinkin of just busted the rivets out. But back to my blowning dimmer switches. I put a good one in, works for about an hour then the instrument panel lights flicker an shut off.... None of this happened till i hooked up the light for my fuel pressure guage, an someone said that i may have disturbed something that was on its way out. Any suggestions???

well after i did it the first time, i un hooked the f.p. guage light, an got another dimmer switch... that one lasted about an hour, then as im about to pull out of the driveway it went out... on to the third one. Just like the second one worked great for awhile... went to go to the parts store an no instrument lights came on. On to the fourth, which worked fine till i went to leave the guys house whos paintin my car.... so i came home all pissed off an what not.... crawled under the dash to test the fuses an they all checked out... just went again for a second look, an sure enough i dont know how i missed it, but a blown fuse.... replaced it, an dimmer's workin great at the moment... i dont want to use it too much though, cause ive gotten to the point where im tired off messing with it... next im just gonna pull the dash out an look for any fraid wire....

well i dont know why it is doing this, but now its blowing fuse 13... Im about to say the heck with it, an just rewire it.... thanks!!!
